Sky has today rolled out its new catch-up TV section on the Sky+ electronic programme guide, as well as announced a new set top box with 2TB storage and added Zeebox functionality to its Sky+ iPad app.

As announced earlier in the month, a raft of changes and improvements are being made to the Sky+ guide, which is now used by over nine million homes in the UK.

The headline new feature is the arrival of catch-up television in the new On-Demand section of the EPG, replacing the previous Anytime service.

Launched over a decade ago, Sky+ now generates 1.2 billion sessions of 'time-shifted' (away from the live broadcast schedule) viewing from Sky customers every month.

Sky previously offered a maximum of 1 TeraByte of storage in its Sky+ set top boxes, but coinciding with the launch of catch-up TV on the platform, the firm has announced a new Sky+HD 2TB box.

Created in response to customer demand, the new 2TB box has six times the storage of a regular Sky+ HD box and can hold up to 350 hours of HD content, equivalent to more than two weeks' worth of viewing.

"Since launch, Sky+ has led the revolution in how we watch TV and let more than nine million households take control of their viewing," Luke Bradley-Jones, Sky's brand director for TV Products.

"We're pushing forward again by offering customers even more flexibility, more personal storage and entirely new ways of engaging with their favourite TV.

"With customers using Sky+ a staggering total of more than a billion times each month, it remains the gold standard in pay-TV."

Also announced today by Sky is a new way for satellite pay-TV customers to interact with their viewing via the Sky+ iPad app.
